To all whom it may concern.'

Be it known that 1, Joux Lier, e citizen of the United States, residingot Detroit, county of lllayne, State of vlichigan, have invented acertain new and useful Improvement in Space-Band Cleaners, and declarethe following to be a full, clean, and exact description of the same, sch as will enable others skilled in the art to which it pertains to makeand use the same, reference. being had to the accompanying drawings,which form a part of this speciication.

This invention relates to space band cleaning devices and its Objectis asimple and efficient machine for automatically cleaning space bandsemployed in linotype machines or the like. A

During the casting o a line of type, the space bands become more or lessleaded after a short period ot use, and it is nece,- sary that thesebands be kept perfectly clean to produce the most satisfactory result.

As a great number of space bands are used that continuouslyY requirebeing cleaned, itis an object of the invention to provide a Cleaningdevice that is not only automatic in act-ion but that operates in amanner whereby each space band is rapidly and thoroughly cleaned anddelivered in a stack for ready removal from the machine.

These and other objiects and novel ieatures of construction arehereinafter more fiilly described and claimed Chorin in the accompanyingiran Figure 1 is fr side elcvatiiin of the device embodying myinvention. Fig. 2 is a sec` tion on line i12- of Fig. 1. Fig. 3 is asection on line yg/ of Fig. 1. Fig #i is en enlarged elevation partly insection of the polishing rolls showing the race-Way by means of whichthe bands are fed to the carriage. Fig. a detail of the brush forapplying graphite to the polishing roll. Fig. 6 is a detail inperspective, showing a portion of the carriage, the race-Way fordelivering the bands to the carriage, and the racefivay for receivingthe bands from the carriage. Fig. is c detail' ot' the friction clutch.

In the prefe red Jr'orm shown, 1 is a suitable frame or casing providedwith a cover niember 2. The cover member is fouled with a chamber 3 inwin ch a, pair oi polishing rolls .enumerated parts.

with intermeshing gears 8 and 9, and the shaftextends through a bearingat the rear of the casing 1. Upon the outer end of the shaft 6 isloosely mounted a Worm Wheel 10 which is driven through the medium ofthe Worm 11 on a shaft 12 of an electric motor 13` the frame 1 beingpreferably provided with an inclosing casing for the Secured to the`Worm Wheel 10 is a circular casing 80 Within Which is an expansiblering regulated by the hand wheel 81, the Whole forming a friction clutchthrough the medium of which the Worm Wheel is secured to or loosened onthe shaft. The ring is secured. to the shaft 6 and by turning the handwheel 81 and expanding the ring to tightly engage the casing 80 theshaft 6 is made to turn through rotation of the worm wheel 10 by themotor. By such arrangement injury to the various parts is prevented incase the machine becomes accidentally stalled, as in such event, thecasing S0 may revolve about the inclosed ring and thc shaft C and theparts operated thereby remain idle.

Mounted in bearings inthe casing 1 is an idler gear 14 meshing with a.gear 15 on the drive shaft 6. 0n the shaftyof the idler gear 1% a gear1G meshing with e gear 17 on the shaft 18 mounted in bearings in thecasing 1. which gears areI all driven through the medium of the driveshaft 6, which by reason of its connection to the motor has the highestrate of speed, While the shaft 1S has the lowest rate of speed. rThecarriage 19 for the space band is U shliped as shown more fully in Figs.2 and 6, beting formed with two upwardly extending spiced members 2O and21. The upper end of each member 20 and 21 is provided with a lug 22having a sharp undercut upper edge 23 to engage the side extensions 31on the sliding portion 46 of the band as hereinafter more fullydescribed. At the rear edge the carriage is provided with a latterlyextending flange portion '24 Which'rides in a: slot 25 provided in thecover member 2 and is held therein by the retaining plates 28 lforming aguideway for the reciprocation of the carriage. To the lower end of thecarriage 19 is secured a stub shaft 27 connected by a, link 26 at therear of the machine'to the crank on the shaft 18 as shown more clearlyin Fig. 2. The rotation' ot the shaft 18, theret'ore reciprocates thecarriage in the way 25.

Supported upon the front of the machine is an inclined raceway 30, inwhich the used space bands are placed in consecutive order, theprojecting lugs 3l on the band ride on the way 32 provided upon eachside of the raceway. Below the raceway 30 is a guide rod 90 whichengages in the slot formed in the lower end of the space band. Thisguide rod prevents the bands from twisting in the raceway 30. In slidingdown, the lowermost space band is picked up by the lugs of the carriageand raised by its continued movement between the polishing rolls 4 and 5on the shafts 6 and 7, the direction of rotation is shown by arrows inFig. 4. The roller 5 is carried in a yoke 33 shown by dotted lines inFigs. l and 2, the lower end of which is pivotedto the shaft 18 and thisyokcris held in position by a spring 34 so that the polishing roll 5 ispressed into engagement with the polishing roli 4, the purpose of whichis to allow the roll 5 to ldraw away from the roll 4 as the w413 to holdthe raceway lwith the for wardl end thereof against the upper portionA44 of .the raceway 30, as is seen more clearly inFig. 6. As the carriage19 moves upward -with a space band therein, the race way is raised bythe upper end of the band, and, as the band passes upward with thecarriage, the end of the raceway 40 drops into .the slot 45 in the spaceband whereby, on the return of the carriage to its lowermost position,the upper-'sliding portion 46 of the band engages -the raceway 40 and,as the carriage continues to descend it draws away from the band whichis thus delivered onto the inclined raceway and down which it slides.The continuous operation of the carriage therefore, takes -a band fromthe raceway 30, raises it between the polishing rolls and finallydelivers it onto' the receiving raceway 40, As the receiving racewaybecomes filled, the operator may turn the raceway on its pivot and stripthe,

cleaned space bands therefrom.

The polishing rolls may be of any approvedtype for the purpose, but arepreferably of metal, which is grooved or scored on the face at an angleto the longitudinal axis. These grooves are preferably filled withgraphite or other material suitable for the purpose. The bottom of thechamber 3,

-ably provide a receptacle 60 near the i? in which the polishing rollsare situated, is formed in a manner to hold powdered graphite or otherpolishing powder, and the polishing rolls are continuously supplied withfresh powder by means of brushes 50, im shown more clearly in Figs. 1, 4and 5. The bristles forming the brush are mounted in a head 5l, throughwhich a rod 52 extends pivotally supported in the walls of the chamber3. To the outer end of the rod is an operating lever 53 extending downward below the bottom of the chamber and inwardly' toward the coverplate 2, terminating in a curved portion 54 positioned in the path ofmovement ofthe portion 24 of the carriage 19. The normal position ofthese curved ends of the operating levers is shown in Fig. 1, where theyare seen to be practically in contact, and the bristles of the brushwill then lie in the powder pro-- vided in the bottom of the case ai, cl3. Upon the upward movement o t riage, the rounded upper end 55 oil. thec tion S24- engages between the curved ends of the levers forcing themapart whmh rotates the brush head upon the pivots provided and bringsthe powder covered bristles in Contact with the polishing rolls and thusvsupplies fresh powder thereto. As the car,-

riage descends the brushes fall back into the n powder by reasonof theaction of the coil springs 56 tending to hold the brushes cui of Contactwith the polishing rolls. At cach operation of the carriage the rollsare thu. supplied with fresh powder.

During the polishing operation consider-v able polishing powder willfallthrough the opening in the bottom of the Vchamber through which thecarriage and space band reciprocates and, to prevent waste I prefer ofthe machine to receive the powder wh may be again placed in the chamberthrough an opening provided in the o thereof.

Iliff From the foregoing description it he. comes evident .thatthedevice is of simplifand compact construction and is automatic inoperation, it simply being necessary in supply the raceway 3Q with theused bands H5 and to remove'the cleaned bands from the raceway 40. Theband iscariied to and from the polishing rolls by the carriage is thusguided in its movement.

Having thus brieiiy described my inves 5 tion, what I claim and desireto secure h 'f Letters Patent of the UnitedStates is- 1. In apparatusot' the kind described. polishing device, a l'aceway for holding aplurality of space bands, a reciprocahif holder` or carriage adapted toco1 ..'ecutively remove the bands from the raceway and suhmit each to apolishing operation by thel polishing device, means for positively reciprocatmg the carriage, and automaticinean for removing lhe polieliedhunde from the holder.
